let me add that all PBKDF-s can be naturally and easily extended to
support server relief. all we need is to add a final hashing step:

K = H( PBKDF(pwd, salt) )

the server can request the intermediate result, and do the
hashing only.

also, any PBKDF can be used in advanced schemes, like SRP.

these are all orthogonal to the PBKDF itself.
